Figure F28. Age-depth plot for Hole U1351B. Sedimentation rates are tentative and based on visual data correlation. The presence of hiatuses is inferred from rapid shifts in faunal ages and "soft" biostratigraphic data such as assemblage ages and rapid shifts in assemblage types (especially in reworked nannofossil assemblages). Hiatus positions are sometimes located at distinct boundaries found in recovered cores, but some hiatuses exist in intervals of low recovery. Dashed wavy lines = the most poorly constrained hiatuses. NZ = New Zealand.
